To a/ZZ whom it may concern:

Be it known that I, JAMES T. TAYLOR, a citizen of the United States,residing at Houston, in the county of Harris and State of Texas, haveinvented new and useful Improvements in Fireproof Nailing-Brick, ofwhich the followingis a specification. l

This invention relates to an improved tireproof brick or block to beused as a substitute for the Wooden blocks, strips, and plugs now ingeneral use, such wooden pieces being inserted at certain intervalsbetween the course of lbricks` for the purpose of enabling the interiorwoodwork to be nailed thereto. The employment of wooden blocks, plugs,strips, or the like is objectionable for many reasons, among which maybe mentioned that they frequently split and render the hold of the nailor nails insecure, that they decay under the iniiuenc'e of theatmosphere, that they shrink and draw away from the masonry into whichthey are built, allowing the same to work loose,

and that they lncrease the danger of destruction of the building in theevent of tire. f

It is an object of my invention to produce a reproof brick or blockwhich shall be of a porous character,to enable nails to be driventherein, and which will be free from the objections above set forth. Y

In order that my invention may be clearly understood, I have illustratedthe same in the accompanying drawings, in which Figure 1 is a horizontalsectional view of a brick or block constructed according to myinvention. Fig. 2 is a cross-section of the same. Fig. 3 is a detailedview showing the strengthening structure.

Proceeding according to my invention I form a composition of Portlandcement, cinders, coke, and sand in substantially the proportions, byweight, following: Portland cement, one part; cinders, iive parts; coke,one

part; sand, two and one-half parts. These ingredients are mixed with asuitable proportion of water to form a plastic mass, and from this massthe bricks o'r blocks are molded and dried in the usual manner. The cokeused is f preferably in the form of grains of one-eighth 5o of an inchin size, and the addition of coke in and desire to secure by 1 1 LettersPatent, is

this form to the composition is for the purpose of rendering thefinished product porous in character. I employ coal-cinders--that is,unconsumed particles of coal-as distinguished from ashes or fromordinary furnace refuse, and said cinders are carefully freed from allslag, clinkers, and the like, as these latter ingredients are fused toohard to permit the driving of a nail through the brick and besides wouldrender the same'heavy and dense,

whereas I aim to produce a light highly-porous brick. The use of cindersand coke crushed to a certain neness-viz., to about one-eighth of aninch-produces a `high degree of porosity and enables the block to yieldto the nail, while at the same time rendering it capable of holding thenail as iirmly as wood. The sand and cement furnish the materialnecessary to produce the requisite density and strength.

While a brick or block formed of the materials named will ordinarily bestron g enough to permit nails to be driven therein without cracking orbreaking, I have, nevertheless, found it desirable to absolutely obviatethis occurring by strengthening the brick in the manner shown in thedrawings-that is to say, I mold in the brick woven wire 1, which is inthe form of sheets extending around the sides and end of the bricks at asuitable dis- 8o tance therefrom and of slightly less height than thebrick, so that said woven-wire sheetsi will be entirely embedded in` thebrick or block. As shown by Fig. 3 these wovenwire sheets are in theform of a rectangle, the opposite sides of which are connected at suitable intervals by diagonal wire braces 2, said braces crossing at thecenter of the brick 3. Any desired number of these wire braces may beemployed. 1

A brick or block constructed according to my invention will be reproof,will not be deleteriously aiected by climatic conditions, while at thesame time it will be much stronger than an ordinary wooden block, Theaddition of the strengthening structure of woven wire prevents alllikelihood of the block breaking or splitting when nails are driven intothe same.

vItwill be'understood tially, of one part Portland cement, five partscinders, one part coke and two and one-half parts sand.

In testimony whereof I have hereunto s et l5 my hand in presence of twosubscribing wit- DeSSeS.
